https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D243126 --- Comment #10 from commit-hook@freebsd.org --- A commit references this bug: Author: pkelsey Date: Sat Mar 14 19:55:06 UTC 2020 New revision: 358997 URL: https://svnweb.freebsd.org/changeset/base/358997 Log: Remove freelist contiguous-indexes assertion from rxd_frag_to_sd() The vmx driver is an example of an iflib driver that might report packets using non-contiguous descriptors (with unused descriptors either between received packets or between the fragments of a received packet), so this assertion needs to be removed. For such drivers, the freelist producer and consumer indexes don't relate directly to driver ring slots (the driver deals directly with freelist buffer indexes supplied by iflib during refill, and reports them with each fragment during packet reception), but do continue to be used by iflib for accounting, such as determining the number of ring slots that are refillable.
